Its like you need a list of laws rules and enforcement "we" people have built to stop "them" (corporations/governments/groups of lobbyists) from working together.
I'll point to the gun rules, where gun owners prevented the state from building gun registries, forced gun sale records to be kept on gun store premises, and then largely purchased from small independent gun stores. They ensured the background check was on the person and not the gun. All intentionally with the understanding that someone somewhere was going to attempt to grab the power of who had what guns.
You can avoid giving any single person or group too much power. It does take effort.
