It's absolutely fair. These are separate statements, and they're both true. Tesla has missed "some" (only some?) deadlines. And they've also brought EVs to the public. It's completely fair to say these because they're true.
Until something is delivered, and bug-free, I don't really believe anything they say. They've done a lot, but their word is next to worthless.
I have Starlink as well - over promised, and under delivered _but_ it currently still has no competition in my area.
The difference is that Tesla now has competition, but they did still have some good ideas. If NACS really is open and free, I don't see the big deal.
