It’d be best to stay on topic and focus on PSS. This proposal isn’t about how Stride does its delegations (which up to Stride governance). It’s about Stride’s PSS configuration.
Addressing your points briefly:
Stride didn’t force Hub validators to do anything. The Cosmos Hub decided to add ICS, onboarding Neutron, Stride, and others. Then, the Cosmos Hub voted to onboard Stride here.
You’re mistaken about how LSM delegations work. LSM delegations aren’t persistent, they rebalance frequently. LSM delegations go to a smaller set of validators because LSM validators must have a higher self-bond to accept the delegations. But the validators lose those delegations soon after they receive them, and they are distributed to the full set. LSM delegations aren’t a revenue source for validators.
But again, it’d be best to stay on topic and focus on PSS and the proposal at hand.
