Would I be right in assuming it's not the existence of forkcoins you oppose, but rather just the false advertising part to sucker in new users?  Because I'd argue that being opposed to forks unconditionally simply isn't practical.  If people vehemently want to incorporate ideas into Bitcoin that are fundamentally incompatible with its underlying principles, do we really want them to stick around forever, still desperately trying to inflict their delusions on the Bitcoin protocol?  Surely it's better to excrete such toxins?  It's never "dilution" to release waste.  Let them build their faulty clones and pretend it's the real thing.  I'd argue it's still preferable to an alternative outcome where no forks had taken place and the toxic "blocksize debate", instead of being a footnote in the annals of history like it is now, had still raged on to this day because those people never got what they believed they wanted.

The fact they still market their shitcoins as "Bitcoin" is inexcusable, but they're off doing their own thing now, leaving us to get on unopposed with our thing.
