Penalized for not buying Premium?

Due to medical disability on a fixed Veteran’s income I can’t afford Premium I did the free trial for a week Now I’m penalized after 4 years being part of the SA users. Suddenly articles say, “ you have reached the end of your free articles” they were always free as long as you didn’t touch the Premium Trial..so the policy is don’t buy the Premium..be gone? Really..confirm this policy and I will. Tell me this a glitch..I have a much higher faith in SA
