Apple is leveling the playing field and this moves makes perfect sense for Apple and everyone else. Apple management (probably like the rest of the industry) under the assumption that the company that's selling repair friendly products will inevitably lose revenue and market share, is less competitive than the rest. So it's a game of "first one who moves, dies first".

If a company wanted to change the market, the only viable option is to go through legislation, because the internal company goals that might actually be repair friendly is then forced on all the competition as well. Leveling the playing field.
