Fun rant to read, but this is an entitled view. Not everyone has to have a website, or has to care about democratising the internet. If you don't want to do business with them just because you shun platforms, that's up to you. They may be doing just fine without your patronage.

I don't do business with them because I can't access their hours, menu, services, etc... I've had this happen a few times. I'm not avoiding these businesses because I'm a snob. It's because I literally can't access the information. So, I go back to google and find a business that provides the information I need to decide if the business meets my needs before traveling to their location.
