How to bypass isp limit by routing through a specific website

The title is somewhat accurate idk how to describe it.

So my question needs context. My isp is a piece of shit monopolistic assholes. Who hard caps at 6mbps or 700 KB/s and blocks all cache servers in the name of security and charges high . So today i noticed that in the wattsapp website i can download the exe file at 9 MB/s .

So can i mask and route through this site and get this speed somehow with other downloads such as steam or torrents ? It would really be helpful as downloading games at 700 KB is a pain.

Idk if i made any sense but any help would be much appreciated
