And then there are the numerous cases of abuse involving athletes and coaches.
I wouldn't say that FS stands out when we compare its number of abuse cases with the numbers of abuses cases in other sport, entertainment, or professional environments.
Also, I don't think that we watched radically different sports, so...
Shall we take this straight to a thread which is specifically devoted to discussing PCS?

Or, not. It seems that PCS has been discussed in almost any thread lately. So why not here?
When I started watching figure skating, I was blessed to have really good commentary that included the explanation of PCS that most commentators never explain. I guess that it helped me a lot and that's the major difference between your experience and mine.
So, regarding your examples...
- It is widely accepted for skaters in the earlier groups (and from weaker federations) to receive lower PCS compared to those in the later groups.
Skaters from earlier groups and weaker federations tend to receive lower PCS but it's not because it's "widely accepted". First, the federation: being a weaker federation means smaller human resource, fewer ice rinks, weaker inner competition and weaker international skaters as the end result. Weaker skaters accordingly receive lower TES and PCS
The "last warm-up group PCS" is a different issue; although I would not rate it as an issue but rather as a logical outcome of the existing PCS judging. Currently, the PCS is awarded based on the visual comparison of skaters. It is easy to compare skaters when they skate back-to-back in the same group; not that easy to compare with skaters who skated an hour ago. That's why skaters receive their PCS pretty much in the light of how other skaters do in their gruop. In the free skate last warp-up group, judges know for sure that they compare best with the best and they don't spare their GOE and PCS. In earlier groups, they sometimes do. A lesser known skater may get higher PCS in the last group if he/she is as good as the best; however, if he/she isn't, the judges may be particularly harsh on PCS because the comparison with the best makes it look worse.
I would would wish better tools for comparison and, the best would be objective points of reference for PCS. But this has been discussed in other topics more than once or twice.
- It is considered normal for skaters with higher technical content (read: more quads) to also receive higher PCS.
Do they? I mean, has Malinin ever received higher PCS than Kagiyama?

I need more facts for this example.
- PCS (which used to have five categories: Skating Skills, Transitions, Performance, Composition, and Interpretation). Itās very rare for a skater to be strong in all categories, but you wouldnāt know it from the scores.
The very idea of PCS is to evaluate the program as a whole, not being splitted it in several different categories.
That's why they are called "components" and not "categories" or "fields". There are the supposed compounds of one end result that in theory can't be judged separately. That's why, when you look up the PCS requirements, you can see that they are subtly intertwined.
For example, for the Presentation component, the criterion āExpressiveness & projectionā has the explanation:
Through complete personal involvement in the program, the skater(s) express(es) and project(s) a mood, feeling, image, rhythm or style as inspired by the musical selection and by the specific style of the dance. Confident presentation of oneās body and energy to communicate a feeling. Ability to capture the viewer, to arouse emotions. Even the weakest emotionally invested skater would get 10 points according to this if not the section in bold that relates this criterion with body control (Composition component) and energy (Skating Skills component). So eventually, the one who expresses emotional investment via greater speed and more elaborated body movement will also get higher Presentation component.
- Ice dancers often have to compete for many years and wait for their āturns.ā
Ice dance is a category in which more years of practice lead to better skills. This is normally a hard-to-beat advantage unless the younger team comes with a technical breakthrough in another area that outweighs the clean edges of the older team.
- Skaters are not allowed to question their scores, etc.
They are allowed and they do ask all kinds of questions regarding their scores. They ask the judge who represents their country and the judge then does the "splaining" (at least our judge does). It does not affect the historic result but it can provide the skater and the coach with the information regarding what they need to improve.
If something looks like a major injustice then there can be filled a major protest via the skating federation that addresses ISU or the national judge or the head of the national judging committee addresses the ISU judging committee. This also does not change the historic result but it may prevent similar major injustice in future.
There is certainly place for discussion regarding all examples that you mentioned but I hope that I clarified some popular misunderstandings here. Or, I did not
