The implicit claim being made in this sarcastic comment is that it's not possible for a law to be detrimental to one company while unfairly favoring another.

Which, of course, is obviously false when you think about it.

Which major tech companies would it be good for while being bad for Apple? Keeping in mind that the owner of a device is also allowed to repair without certification.

Where did I say "major"?

The OP said "a giant handout to the industry". If you're trying to make a point that excludes all the major players in the tech industry then by all means go ahead but it isn't the conversation you joined.

I imagine the parable of Brer Rabbit and the Briar Patch is largely lost on today's audiences. More's the pity.
