So, in the name of science I had suport disable it on one of my accounts to actually try it. Pros - it was actually fast. Opened a ticket, asked to disable hypernet, was done within an hour.
Now, how it looks → The relay link in finance is gone. The spam is sadly not, so channel filters are still necessary 
But clicking the link will not open it:
Overall, I rate this implementation 7/10 . Would like the hypernet urls to not render at all, but it’s nice they actually disable the whole offer display. I guess when I have time, I’ll go over all the accounts to do it.
