I feel his arguments always miss the simple fact that he has no idea how much trouble not-including such restrictions actually cause, and he over-estimates his audiences' skill/underestimates his own skill, muchless over/under-estimating his willingness to accept responsibility compared to most consumers.
The software I work on has a simple database we use to manage the configuration, and it's a CONSTANT battle with "knows enough to be dangerous" DBAs/IT persons to argue that we're not going to fix the DB after they went through and did their own edits to try to fix an issue and the end result was they only made the situation worse.
The argument of "well, publish more info on the DB" falls flat for me as we constantly published information on which program versions and what specific issues the edits applied to, and our clients simply didn't care; our clients aren't just average users, they're allegedly IT professionals like anyone you might imagine reading HackerNews. We had cases that lasted for months over who was responsible for the issue when the client clearly admitted they just hacked the DB with a chainsaw.
Rossman has some great knowledge and I absolutely do agree with his position on Apple making it too hard to repair their stuff. (Based on the most recent MacBook Pro, seems Apple also agreed...) But I think Rossman fails to appreciate the scale that many companies are dealing with and the sheer volume of customers who absolutely screwed up such rudimentary repairs and then try to blame the company for [the customer's] own ineptness, and how a lack of legal language to specifically protect the company from such behavior opens up very long and difficult legal and PR battles.
Rossman has good knowledge, but I don't feel he's giving a good faith interpretation as to where such policies and ideas come from, and he'd be far more effective in his communication if he simply left his videos at the point where he demonstrated the simplicity of the repair without the tirade. I don't know what Rossman's liability policy looks like for the repairs he does, but I don't get the impression he takes on a lot of liability compared to what I've dealt with across many different products.
