It is absolutely an opinion. Your metrics are right, but "it's a failure" is absolutely an opinion. It's your opinion, based on what you place value on. Mastodon is not a failure to the 200k people that use it, it's a success to them. Thats their opinion, because they value different things than you. "194k people use it, that's more than the populations of 20 sovereign nations! That's a success" has correct metrics, as correct as yours, but using that to call it a success is an opinion. Just like your statement is an opinion.
