Some rather sensationalist claims there. Other than infringing on the DFSG, I don’t really see the problem with those binaries.
If you’re downloading compiled software from anyone, you’re trusting them to not have put nasty things in the binary. There could be lots of interesting things injected to the binaries that are not part of the open source code.
As for the safe browsing thing, that looks to be a bug specific to Debian’s Firefox-distribution, not FF itself.
And as for DoH, it’s not exactly a secret, it’s been widely reported on and featured in the release notes. If you’re technically competent to play around with `/etc/hosts`, you should be capable of reading the release notes, too.
