I think we're at the point where there is a bit of healthy competition in the EV space (even when excluding the Chinese), that Teslas are mostly just symbolic.
People still buy Teslas. But in my circle, most have bought other EVs (and not just because of Elon). Teslas are no longer the obvious superior choice.
Since I'm in the US, BYD is not part of the equation.
And yes, I will grant that at this point, it's possible that Tesla has the least serious problems. I don't know - I haven't looked at recent data. But it's the usual trajectory: I know plenty of people who bought Teslas in the last 5 years and complained how many weeks/months it would sit at the dealer awaiting repairs (just like it is with Hyundai/Ford/everyone-else these days).
Case in point: Pretty much everyone I know who bought a non-Tesla and had issues with it is still happy with the purchase. Just like Tesla users of the past ;-) Only one guy got annoyed and sold his car and bought a different non-Tesla EV.
My point is that if Tesla suddenly dissolved tomorrow, existing automakers will continue improving their vehicles. Maybe 10 or even 5 years ago Tesla's death would have meant the end of EVs in the US. But by this point we've hit critical mass. They're here to stay.
There are just so many non-Tesla EV choices now.
I think there is still a (brief) remaining window where Tesla has an advantage in the US, but it is too late for them to start developing new models to take advantage of it - and that is NACS and the SuperCharger network. Now that new EVs from everyone else are coming out with NACS and are on-boarding plug and charge (and, hopefully, mapping integrated with charging availability), all US EVs will be just as easy as Teslas to take on road trips.
I still think there's a benefit to sticking with EVs from companies that are actually "all in" on EVs. Otherwise you're buying the product that the company (or really the sales/service channel) really doesn't want to sell you.
In this space, Tesla does have competition (e.g. Rivian and Lucid), but nowhere near as much as they should.
You might be surrounded by people who stopped thinking. My friend said "hell no" to Tesla right around backlash started and ordered a PHEV. Thankfully, somehow, someone convinced him to upgrade to EV. I keep begging him for a drive, but I suspect he's embarrassed by how shitty BYD is (same with other mate who somewhat regrets with all the issues he had, albeit they were far cheaper back then).
