Well Apple is notoriously abusive of the developers on its platform. Two things are particularly cried about across most of the ecosystem: the 30% cut they take off pretty much everything and the vague terms that you have to comply with, and that they enforce in a mostly random way (app gets pulled out of the app store, won't tell you why, won't tell you what you did wrong).
Now add the exhorbitant prices for their low-specced, low-quality hardware.
Now add the continual rip-off of their users.
Now add the subject of the original linked page.
At this point I think that yes, defending Apple is extremism.
It's fine to accept the tradeoffs, it's not fine to pretend they do not exists:
- "Yeah this stuff is unreasonably expensive but we have to use it"
that is honest
- "the apple ecosystem is the best for creative and developers and what apple does across all the spectrum is fine"
that is dishonest.
