All major corporations are going to be the enemy of decentralization. So are the governments of the world. Anything that can't be regulated and monetized.
I predict:
* Google will do the same thing at some point - sideloading will be the only way to use Nostr apps
* If Nostr grows to any significant size, there will be congressional hearings
* A relay operator will be arrested for hosting illegal content at some point - probably unknown to them
* The former two points will likely be related
* Both app stores will ban Nostr apps over moderation, not lightning
* Apple will eventually enable sideloading globally, because the US will not like being left out of the EU's freedom
* Apple will adopt lightning (as will Google) just as soon as the government has figured out how to regulate it (which they will)
* People will still find ways to dodge being tracked with Bitcoin, and those ways will technically be illegal - and people will do it anyways.
Time will tell.
