It seems to me that his problem with it boils down to the odd case of someone trying to ruin an online game to make the developer abandon it and then host it themselves to make money from it. This would only be a problem with free or very cheap online games because to have bots to disrupt the game you would have to buy an account for each of these bots. That would become very expensive very quickly.
There’s a reason why it’s named Libreoffice Impress.
