I have a 2019 Tesla, which I bought specifically due to their charging network. That network is now open to other manufacturers, and most have signed deals with Tesla for integration. I’ve never had an issue with charging, and the longest I’ve ever had to wait for a charging spot was 10 minutes, and that was when half of the chargers at that stop were offline for some unknown reason.

While I don’t particularly want to support any of Elon’s companies at this time, Tesla did do pretty much everything right regarding charging infrastructure, and like you said, the alternatives are very iffy.
