I have friends who own medium-sized restaurants in a couple different major EU cities.
They all have domain names, and web sites sort-of, but none of them thinks anything matters besides Facebook and to a lesser extent Instagram. The web sites are rarely, if ever, updated. Of course right now they are all forced to close anyway; but pre-Covid at least one of them tried to take the web site seriously and gave up after a while, everybody used Facebook anyway.
One of these owners is my age, the others are younger. I even know a guy who owns a catering company and doesn't bother with a web site.
I understand your friends think a social media website is enough. This doesn't mean they need to accept having a website created for them. It sucks that they have to opt out of local delivery services, but it also sucks I have to opt out of junk mail. I still don't understand where the evil is here? It's legal for people to create websites that look and feel similar to existing websites. If this is a problem let's fix it! if it's not, let's not focus on restaurants?
EDIT: Note, the comment I’m replying to grew by about 300% after I posted this.
Let's assume that restaurants don't want people to order their food through delivery. Why don't they just opt out? If they aren't opting out, then clearly the people buying the delivery are paying the same as any other takeout customer? Where is the problem here? What is the thing that gets people so very offended on behalf of restaurant owners? I actively want to understand this!
If people have to pay a large markup, they may end up ordering less food. Or maybe ordering from another place because this one seems too expensive.
The offense comes from delivery companies forcefully inserting themselves between customers and the restaurant. Why not just let customers go to the delivery company's website to order, if that's what they wanted? Why is it necessary to deceive customers?
