When language is tightly coupled to cultural identity, using this kind of fake is lying to voters, saying, "I'm one of you."
It's a new use of technology to repeat an old lie. I think it's a bad thing, but it's hardly the most dangerous and novel application of this technology for evil.
Given that the PR firm who made their video apparently reached out to the press to tell the story, it seems that he wasn't actually claiming or pretending to be a native speaker (and anybody who did would be extremely easy to uncover). Just using a glorified overdub service and being quite upfront about it.
Had he used a translator, it would have been more obvious but possibly had the same effect (if what he had to say resonated with the voters). So what you are against is the idea that it’s not labeled as “virtual translator was used to produce this speech”?
Certainly that's the impression I had from the comment - it's a politician being dishonest, and an undemocratic system which gives non-proportional power.
