You're right, Kaepernick had an option on his contract for an additional year, but he declined that option and decided to test the free market because he wanted a guaranteed starter job and he wasn't getting that in San Francisco. And I'd like to add that the deal with Kaepernick isn't that no team would sign him. It's not even if it was due to his political stance. Kaepernick's entire beef was whether or not the league was colluding to keep him from being signed. To put it as simply as I can: It's ok that teams like the Patriots who don't need a quarterback didn't sign him. It's ok if a team didn't sign him because of his opinions. It's ok is no team at all wants to sign him. What isn't ok is if hypothetically the Browns and the Bills agree that neither will sign Kaepernick. You don't even need all 32 teams in on it, 2 would have been enough.
