For every reboot sequel and prequel there are 10 new series. There are around 40 different new anime this season. (Without counting Chinese, musics, poor quality and children’s show). Take a look at myanimelist seasonal anime.

(Anime in Japan come out in season : winter, spring, summer, fall. So they start and finish roughly at the same time).
.

And most or your example are pretty bad,

• bleach just got an end that everyone liked
• hunter hunter was paused because the author is sick, it never stopped and it’s not a reboot
• FMA brotherhood was great because it fixed the issue with FMA : the end of the anime was made before the manga. And it’s 2009 come on you can’t use that to say that nowadays there’s only reboots
• yeah they are milking the fate franchise and evangelion, and their community is all for it
