> Yes and no. The complaint is that some widely used extensions are proprietary. If these extensions require MS servers, then they have every reason to be. Even if they don't, there's nothing wrong with a company holding back some stuff they consider strategic, they're not obligated to release them.
that is kinda debatable, considering that those are extensions to an LGPL-licensed core (Blink, the rendering engine used in electron) - see e.g. https://lists.gnu.org/archive/html/directory-discuss/2017-12...
