Right but again I think the number of people that will join a forum or Facebook group about the car they just brought is a very tiny percentage. I think Tesla gets away with this because they can and it doesn't impact sales.
Where it probably does is things like the Yoke where Musk said that's all you'll get but now the Model S / X can be had with a wheel. The 3 isn't getting a Yoke so I think that's pretty clear they are walking that back. If removing the stalks doesn't materially impact sales, they won't be coming back. If they get too much push back and sales drop because of it, they'll walk this back sooner or later.
"New new Model 3, now with stalks!"
Also don't forget other cars have areas where they just aren't as good as Tesla. It's always a compromise, no one car does everything really well generally. I'd still say until they fully open up the Supercharger network, that's still a massive draw.
Check this video out, still shows Tesla have a big advantage here:
