I am completely confused by any discussion of "unilateral exit" or "self-custodial" when it comes to Spark. I completely don't understand why that matters, or what those concepts even mean, in the context of an API controlled by one company (actually one family, in this case.) They can just turn off the API at any time and then nobody can exit! If their servers go down, nobody can exit! It's 100% permissioned, right?

Spark's entire trust model is based on the fact that all keys used to sign previous transactions are deleted.

Problem is, it's not possible to prove without a doubt that someone deleted a key, so you need to trust Spark that they really deleted the keys.

If trust is involved, it's not trustless.

Again, why does any of this trust stuff matter if the only way to actually do anything with Spark is to use LightSpark's API endpoints? And also -- LightSpark's entire reason for existing -- until 6 months ago -- was that they were the "compliant" way to access the Lightning Network? Why use Spark/LightSpark in that case, why not just use PayPal or Coinbase or whatever??

You are absolutely right.
