I’ve been very outspoken about my non-belief in intellectual property; I don’t think reading information or making a copy of it is stealing it. On the flipside, these bots are effectively performing a denial-of-service attack on public infrastructure, wasting computing resources, bandwidth, and time that is finite. The internet is for humans first and bots second; I don’t care about bots so much as long as they are well-behaved, which these are not.
My own instance went under several weeks back, then I installed Anubis and suddenly it’s usable again.
Not a fan for a few reasons. Flathub (as far as I know) works on the app store model where developers offer their own builds to users, which is probably appealing to people coming from the Windows world who view distros as unnecessary middlemen, but in the GNU/Linux world the distro serves an important role as a sort of union of users; they make sure the software works in the distro environment, resolve breakages, and remove any anti-features placed in there by the upstream developers.
The sandboxing is annoying too, but understandable.
Despite this I will resort to a flatpak if I’m too lazy to figure out how to package something myself.
