They're not complaining that someone is copying 'their' service or files, they're informing their community that it looks like the people behind it are not contributing back, and how they feel about that.

In general, I find it of little help to judge what are merely opinions as "right" or "wrong". Can't we simply disagree, without one having to be right and the other be wrong? You make it sound like there was only one true way of being, and some ultimate source of truth that we all need to follow?

I personally prefer it whenever I do not have to judge things as "wrong" out of personal emotional hygiene, because anything that I see as wrong will make me sad or angry depending on whether I consider it something I can do something about or not, whereas a different opinion is merely a different opinion and leaves me in neutral.

I personally also do not agree with using the term "gatekeeping" for providing additional paid faster servers; it would only be gatekeeping for me if they were limiting certain files to paying users, which they aren't.
