It’s scammy because the gym business can very difficult unless you have people paying and not coming in.

If something is "unacceptable" to me, then I would not put up with it at all. A gym treating me this badly is unacceptable to me, so I would not sign up for membership with such a business. I may not be able to get much done legislatively, but I don't have to put up with those business practices myself: I can choose to not do business with them. A gym membership is not mandatory in life, the way buying food is for instance.
I feel like when people make bold statements about something being "unacceptable" as we see here, it's nothing more than grandstanding.
