.com is run by Verizon, and .bananas will be by another for-profit company (most likely Donuts).

If the .com prices were to be increased, there will be a huge backlash. As for .bananas, not so much.

.bananas might get blocked at TLD level, .com unlikely so.

There is an agreement for .com and .org (and formerly .net, but not anymore) that registry price increases are capped at 10% a year, and they aren't allowed designate in demand domains as more expensive premium domains. There was an attempt by the .org operators to renegotiate that, but it was stopped by public pressure.

I tend to subconsciously skip over "weird" TLD sites in search results as they are usually SEO spam.
