I don't see this on mine, but I modified the defaults a long time ago.. My new tab page just has a list of 10 (out of 16) sites I added there manually. 6 of those are services I run on my local network.
Hit the gear at the top right of your new tab page. Uncheck boxes you don't want.
Optionally, disable Pocket completely by going to about:config in address bar. Search for 'extensions.pocket.enabled' and double click to change value from true to false.
