The problem is that by making them repairable they open themselves up to legal liability. A phone battery goes bad... it's a few ounces of solvent to burn. An ebike battery goes bad, and it's going to be near impossible for it not to take the structure with it. That's a massive liability. You can buy replacement batteries on amazon for phones and powertools. You don't know where they come from, and I avoid them for this reason. I've seen batteries from reputable companies combust just sitting on a shelf. The idea that any company would sanction anyone to buy shady grey market and use them with their product puts them in the path of unavoidable financial ruin.
