They will offer a degree of privacy which is generally useful but you can't expect them to protect you if you are planning a revolution :)

Email aliases are typically used for account signups so said services have no way of connecting accounts.

PGP is rarely an option here, and usual caveat that email is already a nightmare bad thing for authenticating accounts.
