I don't use the extra social features your complaining about. Many members here who buy lots of books from Kobo want them and it adds to their reading experience.
I have seen firmware change requests, complaints and new features requests from mobile read forum included in new firmware. Their are 2 sticky future firmware feature request threads with total of 2,379 replies. They need your opinion also.

Kobo Firmware is based on Linux open source software and they do not try to prevent your adding features that you or others have developed to the Kobo Reader you own. Kobo Development Corner has these topics.
