First they block access to Youtube API. Now they decide to block access to Google Maps. Free and Open Web BS is just going too far. I don't think there is absolutely any part of the web which is free and open. It is conveniently used from time to time to convince people to contribute to their platforms.
"Free and open web" doesn't mean unfettered access to private parties' services, it means unfettered access to the internet itself. I.e. access to the services on the internet that private parties are willing to let you use.
Most everything on the internet is owned by someone, and the whole meaning of things being free and open is that putting something up is putting it up for everyone. Your interpretation is just "you can use the things I let you use", which is a tautology...
I'm not sure about tautology or whatever (it seems like you're confusing the network for the endpoints), but I'll give you a metaphor.
In the US you are a "free" citizen in an "open" country. You are free to go anywhere you want on open roads. This doesn't give you the right to trespass and go into anyone's private property. If they have a fence up, you have to stay out. If they're having a yard sale, you can come in.
If Alice wants to let Bob on her property and not Eve, that doesn't make the US any less of a "free and open" country.
This is what is meant by "free and open" web. You can attempt to reach any endpoint you want without restriction, but the endpoint itself has private control over whether you are allowed to its contents or not.
Anything less is not actually freedom, because then the endpoints' freedom to determine who can use its private property is being denied.
A web that is not "free and open" is one in which your attempts to reach endpoints are interrupted and allowed or denied by a third, censoring entity. (Usually the government.) It has nothing to do with how those endpoints would respond to you on their own.
The "Open Web" refers to the platform being open and accessible to anyone (which is why, for instance, royalty-free patent grants are essential for any enshrined web standard), but it does not refer to the content that is communicated by that platform
It's a nuanced (and sometimes nebulous) concept, and I don't really understand what the GP post was getting at, but here's a better attempt than mine to get a handle on it by Tantek Çelik:
