That's because the Bocchi the Rock anime was genuinely good, and reducing Bocchi's assets was a good creative decision. It wasn't done because boobs = bad or because masculine sexuality is bad or whatever, it was done because there were other elements besides sex appeal that they wanted to emphasize, both for the series as a whole and for Bocchi in particular.
If they anime had been shit or if they hadn't added anything beyond what they took away, I'd also be complaining about "censorship" probably, because I would probably believe they reduced her boobs for a non-artistic reason.
