Coming from an American perspective, I'd say this is a good thing.
What y'all are seeing is exactly what we've been seeing (and what Europe as a whole - and the world as a whole - has been seeing for thousands of years): the proliferation of new cuisines. Calling them "tacos" is of course a bit of a sacrilege, but there's more than enough precedent for similarly-named food to have wildly different forms (see also: Spanish tortillas v. Mexican tortillas). And aside from that, this seems like your bog standard fusion cuisine - and given enough time, it'll have its own distinct identity, just like how Mexican food now has a distinct identity instead of being "merely" an amalgamation of Spanish and Aztec cuisines.
More broadly speaking, this is the same mechanism by which cultures proliferate and evolve into new cultures. Cuisine is one aspect of this, and here in the US at least it even helps drive that process; food is communication, and being the fatasses we are, we sure do a heck of a lot of it :)
I miss my Mexican tacos...
Isn't that a gyro?
But they usually come with pita bread, while "French tacos" are wrapped in wheat tortillas instead, use any kind of meat(s), have cheese, sauces, ...
It doesn't have much in common with Mexican culture (nor French gastronomy) and is borderline cultural appropriation. If you want a taco-shaped kebab, rather try an Al Pastor.
> Pelonero had never been to Mexico, still hasn’t. “But I’ve watched a lot of series about tacos on Netflix,”
I guess he hasn't watched this one, or he wouldn't dare naming his things "tacos" :

And the "GigaTacos challenge" is just disgusting.
