Should the censored eleven get a blu ray release

According to the Bugs Bunny Video Guide there was actually going to be a DVD release back in 2011 as the shorts were all remastered and there were special features but WB ultimately got cold feet on releasing it.

I can't see WB actually doing that, defending the shorts as a product of there time is one thing, actually officially releasing them in a DVD set is different. That would be a very risky business move to actually release those shorts with the WB name and beloved characters attached. It would quickly become a question of "who is this for?" and "why does anyone need this?" Especially given all the shorts are online for free. From a collectors stand point, I get it, it would be awesome to have to complete a collection of official Looney Tunes shorts, however, I feel a lot of people would feel its unnecessary and be highly offended leading to boycotts of WB.

if it was, I certainly never heard about it.

Not officially no, though some shorts have been released on bootleg DVDs and VHS tapes, I used to own a couple of them as a kid.

I'm surprised nobody mentioned the Thunderbean set. In 2021 Thunderbean released a Blu-ray with all the censored 11 shorts on it in HD (besides Pingo Pongo).

That blu-ray might have been a special set, they seem to take down those down from their website after some time.

True, though many public domain VHS and DVD releases did contain the short, I actually used to own one of them as a kid.
