Like with a lot of features, this will be introduced on so-called premium brands first. Unless you insist on having one of those (which you would probably lease anyway), you can easily avoid dodgy subscription features.
Software-wise, we already lost to monopolies of FAANG. The privileged few use Open Source and distributed sharing platforms, but the general public has little choice but pay recurrent and ever increasing fees.
I have a choice because I choose to have options, but many consumers won't care or understand options are limited to them if they don't take a stand for their choices.
If people who work at these companies want to continue to rationalize these models are ethical, then that is their choice as well. They just shouldn't be surprised when their models are pulled out from under their feet later.
Since oncall and other services showed consumers are willing to incur ongoing fees, I think we'll see each part of the car beyond safety features tied to a sub model with no option to just purchase unless mandated by law.
