It's not really a bug of the site but something I've just noticed. Consider for example DOTA 2.
You can read it's available for PC, Mac and Linux. But if you go to the description of what a PC is you will notice a PC can run Mac or Linux, there are several operating systems for PCs!.
Therefore it should read Windows and not PC. The game is available for Windows and most probably not all Windows will be able to run it but only a few versions (although it's better to check the game requirements for that).
I agree that PCs are predominantly Windows, but identifying PCs with Windows PCs means biasing the language, being less objective and promoting Microsoft as the standard.
To put an example, this is as wrong as writing "Consoles" where "XBox One" should appear. No market share can excuse that bias.
Thank you for your attention.
