Over the Air Update vs Returning to Dealer

Tesla’s over-the-air software updates make other vehicles ‘highly vulnerable to obsolescence’, says analyst | Electrek

OTA updates, now ubiquitous for Tesla, raises the question of why so many other manufacturers aren't doing the same. This was brought home less than 24hrs ago - & realistically, the example could be any manufacturer and/or any model;

Could it be cost? After all, OTA updates necessarily require cell service for each car, as well as 4G transmit receive capability. Do service centers like this notion? After all, the pairs get charged back to the manufacturer. Would seem likely the business model would get cut into, but in the end, save the manufacturer a boatload, despite the vehicles costing more. Think of the time saved. in less than a few hours, an entire fleet can be fixed. With old-fashioned technology, one has to make a service appointment, then get in line, and maybe wait 4 weeks before it's your turn to get fixed. Hopefully there won't be anything tragic that happens in the interim.
Thoughts?

yes, I hate going into the shop for nickel-&-dime things like electric window grunting & groaning on the way up/down. Ironically, one of the last things we took ours in for was a TSB/2nd row seating/secure issue, similar to what many any other manufacturers have been faced with, over the decades. Definitely can't fix everything OTA.
Little known fun fact; Tesla pays good coin for hackers who can get into their system. One fellow, Jason, back in North Carolina is in the top 3. He has a cool YouTube video cracking open a Tesla pack for the sole purpose of making it into a massive home use battery backup. oh, to be so code smart.
