Three problems. First selling to Google automatically put Nest into the "Are they going to sell my home data" category. Denials to the contrary that's Google's business model for everything so naturally people assume it's going to happen. Second rush to market for their smoke detector Protect caused a debacle when it was discovered it was far too easy to silence a real alarm so they were all recalled, etc. Third Nest has no relationship or respect in the home HVAC industry. Pretty much every HVAC tech and owner I've spoken to has a strong dislike for Nest. And while installing the Nest isn't that hard eventually everyone is going to have HVAC issues that need professional repair and people will get an earful about their Nest. This gets around quickly. Of course now there's more competition also by traditional HVAC companies like Honeywell. Although I had a Nest in my previous house when I purchased a smart thermostat for my son for his house warming I purchased a Honeywell just for the reasons above.
