Just created the instance, now the spammers consumed all my email allowances today :( I just enabled CAPTCHA now, now I'm gonna wait till tomorrow how much this makes difference.

While I am glad that they listened to the community. Everyone seemed to forget that you do not have to upgrade to the latest version. If the risks outweigh the benefits it's perfectly fine to stay at the last working version. There is also the possibility of backports (forward ports in this case?) and manual restoration of Captchas to get the features you want out of the later versions if you have the development skillset to do so.

Nope. This is a huge accessibility fail. Any instance that has captcha enabled is locking out anyone even slightly low vision. Everyone should be manually approving all applications. It keeps instances small, and ensures that the fediverse remains distributed. Once we start having a spam problem, we should all just be defederating every instance that offers open registration; make a script to scan for it, and update the blocklist. Nobody should be running that way. If you are, not only are you allowing spam, you're also probably allowing humans who are engaged in ban evasion and other bad things. All posts and comments that come from your instance are in some small part your responsibility. Be at least vaguely aware of who your users are. If you ban one, and you run open registration, how do you intend to make sure they're not the user you just banned, signing up with another email address? We're not big tech, so we don't have the kinds of tools (IP reputation lists, lists of VPN IP addresses, etc) to fight ban evasion in any kind of automated way.

I don't have a responsibility to do anything. This isn't my issue and you can't force me to care.
