Google has done the same thing to Nest Secure. I removed an ADT system from my office because the monthly monitoring from ADT was $39.99 - the ADT system came with the office. I installed the Nest Secure cameras and system myself, even running USB power outside the office through the masonry. The monitoring was adequate - notifications sent to my phone - and Internet storage pricing was acceptable. But as of April 2024 the service is being shut down and I can opt to have an ADT system installed - a $485 value! - and pay a monthly monitoring fee. (Or I can receive a $200 credit on the Google store, presumably to buy some other technology they are going to sunset.)
