Sounds pretty defeatist tbh.
Clear cheaters will get pulled from official results in Zwift. Would you not race IRL if you lined up against people who had 40W worth of kit advantage? Racing whether online or IRL is never a level playing field.
Races on Zwift can serve as a way of really showing your maximal performance, I’ll wager you’ll go deeper trying to hang on in a race than you could on an interval session.
Both TP and Zwift are excellent, not sure why people have to declare their undying love for one or the other.
