They're maybe lobbying that it's dangerous to race E against ICE (which is obviously BS since it wasn't dangerous to race the Alta or the Freeride in AMA Endurocross and FIM superenduro, and also dozens of countries are allowing the Varg to race).
They won't necessarily need to change their tune when they release their own e bike, they know separate e class makes no sense when there's only one manufacturer, which is why Stark is against it. But whenever they join the fun they could be happy to race their ICE and e bikes in separated dedicated series or classes, catering to different crowds with different bikes.
Ironically it would have the unintended consequence to kill ICE racing faster whenever electrics become faster (be it 5 or 10 or 15 years from now). Separate class means no adjustment of the rules to benefit ICE, no artificially holding back the electric performance, pro riders won't stick too long in the "second fastest class", especially when their manufacturer races electrics as well. ICE will stick around for amateurs and the like, also remain popular for some "show" disciplines for a spectator point of view, but the top athletes will always go for the fastest bikes, maybe they'll miss the noise but they'd rather be the fastest guy out there.
