Earlier quoted context omitted.
I think there are definitely some reasonable limits manufacturers shouldn't be expected to reach in terms of easy, intuitive, tool-less end-user serviceability. For example, I think it is unreasonable to expect that a smartphone's battery be replaceable with 0 tools and 0 consumables (gaskets, glues, etc). However, those tools and consumables _should_ be expected to to be reasonably standard and reasonably available.
Why shouldn't smartphone battery be replacable with 0 tools? Why should there be glue involved? It was a standard that mobile phone batteries were easily replacable. In fact https://www.gsmarena.com/search.php3?idBatRemovable=1 returns ~6400 results while not removable returns ~2400 results. In fact that's how most smartphones were until some market leaders decided to move to glue on hard to replace models.
Personally, I prefer the current common design of trading tool-less battery service for size and weather resistance. I want a smaller more durable phone and I am willing to trade away tool less battery hot-swapping to get it.
With that said, let me re-iterate that I think battery replacements in particular should be REASONABLY accessible. I should be able to perform a battery replacement myself with easily available tools/consumables provided by either(/both) the original manufacturer or third parties.
