The web is unfortunately too ubiquitous for this approach. If I get hired by someone, I have to use the website they chose for pay stubs, or health insurance descriptions, or direct deposit configuration, or stock option distribution, or many other life-essential services that an individual has absolutely no control of. Sure I can complain to HR, but it will fall on deaf ears that were sold by a shitty SaaS pitch that made some loser’s life mildly easier in return for a subscription payment.

And that’s not even touching all of the government websites that behave in this way.
