Google didn't just claim that Android was open, they claimed that it was open source.

Then they used anticompetitive tactics against companies attempting to take advantage of that supposed openness to retain tight control.

They have been found guilty of doing this many times in many jurisdictions.

Meanwhile, Microsoft's XBox walled garden ecosystem remains perfectly legal.

This is because walled gardens are not illegal. Anticompetitive conduct in open markets is.

If you want walled gardens to be illegal, you have to do what the EU did and change the law.
