In other words, the criticism is fair but the solution of attempting to freeze time or even try to go back is not right. Sometimes though, when things get very bad going back to the basics and re-do everything can work.

"Who knows whether a new version will be available and usable when the current one stops working?"

With SaaS products the company can go out of business; they can change the product on you without your opt-in, making it unusable (or less usable) for your purposes and there is no way to downgrade to the previous version; they can stop supporting your web browser; your account can get disabled or compromised; new policies and regulations on data retention and privacy could render a particular SaaS product unusable for your purposes.

What are you meant to do if a SaaS tool you depend on suddenly stops working? How do you install the old version and get back to work?
