Think I will just decline updates

My truck just asked to update, read what the update was for and it seems like it was just for Onstar and google assistant. Declined update and gave the whole would have to be taken to a dealer if I wanted it.

Cleary could care less about the google assistant and Onstar. System seems to be working ok otherwise and thinking of declining further updates. Its a 25 for reference. What are your alls thoughts?
