How would it not be open and transparent on twitter? It's a site where everyone can see what they are talking about. It's only when they try to limit to whom and where they talk to people that they are not open and transparent.

Lying. Trolling. Bullshitting. Stonewalling.

I don't need to talk to you or use your favored public platform for my published material to be open and transparent on some other public platform.

What do these have to do with open and transparent communication?

Very true, but limiting the platforms limits the openness and transparency. With some simple software you can post to all with almost no effort. Seems weird to disclude one just to write a blog post about it for attention.

If I'm lying to you, I'm being neither open nor transparent, by definition.

It only limits the audience who will see it incidentally. Anyone who's looking for it can still find it.

I rather suspect that they are avoiding the platform for reasons other than the effort it takes to simply create a post. This seems moot in context.
