The EFF article is pretty recent and it doesn't look good either. I haven't come across ongoing work for a port of uBO to MV3. If there isn't, that says a lot as well.

Whatever MV3 may offer, I for one do not want adblockers to be compromised. If anything, they should be more powerful rather than less. Hypothetically and optimistically speaking, even if a MV3 port of uBO offers 80% of the current functionally, it would still be detrimental for browsing the "modern" web.
