They have already shown themselves to be both able and willing.
Hopefully the backlash from this current decision will delay their plans long enough for GrapheneOS, Lineage and others to figure out how to work around it somehow, which is why I'm eagerly watching where this is going.
I can't confirm this yet but with Google refusing to provide device trees for new Pixels things definitely look headed that way; they're at least starting to make installing an alternate OS difficult. The Graphene devs are trying to set things up with a handset manufacturer to ship a GrapheneOS phone, but good luck connecting that thing to a US carrier (who allowlist handsets and often limit the allowlist to models they sell directly).

So you're just speculating.
