This exactly. The fact that uBlock Origin has anything from them in their block list is telling. They became the worst, there is no coming back from the that.
There are the individual, commercial, and private blocks and hosts files which have been created and which have to be individually cleared. Possibly IP blocks as well. As with "inheriting" a former spammer's domains or IP space for email, that damage is long-lived.
Securing a new or alternate donain would be a good investment.
While there may be some tech and projects worth continuing, the brand is blighted property.
