Until recently, I was using the Adobe suite extensively. I decided to switch to a competing software exactly because of the practices mentioned in the article.
I don't want to elaborate unnecessarily, but I can confirm that these accusations are absolutely valid, and I even recently told my friends about how unfair Adobe's practices towards consumers are.
I also personally know someone who decided to block their payment card at the bank because it was the only way they knew to free themselves from Adobe's subscription.
