Freedom of speech and assembly, security in one’s person and affects, freedom of movement/transportation, even prohibition against slavery (even though that will be a bit too abstract for most), etc.
Google isn't the government, so the first amendment doesn't apply. Security in one's person and affects? The OP still has possession of their apps. Google is just deciding it won't sell them for the user.
And prohibition against slavery? It's both laughable and deeply offensive to consider this situation even remotely similar to chattel slavery.
