Migration to 4G/LTE network - a pretext to change Security monthly plans?

Follow up to the above. Upon insisting, I was provided with a detailed list of the hardware and a breakdown of the monthly invoice before changing to the monthly plan. The new plan has a lower monthly cost and includes more sensors/detectors, the option to add a doorbell camera device and the Online Security feature (identity fraud protection). It also replaced (at no cost) the existing panel and sensors and added a free smoke Detector. After switching, I'm paying a monthly fee 27٪ lower than before which now includes detectors for CO and flood (which I've purchased). The smoke and flood detectors slightly lowered my home insurance. My current doorbell (Skybell TrimPlus) is not compatible with the Telus system which accepts only 2 models from Skybell and 1 from Alarm.com. There is the option to add up to 2 visits per year to the property by a security team for $5/month. They offered a contract option of 3 or 5 years. I picked 5 years due to the very attractive monthly cost (less than half of what is advertised on their website). Please note that cancelling before the 5 years is up is costly! They do allow transfer of ownership or moving the services to a new home.
Overall, I'm satisfied with the outcome. I still wish they would have been forthcoming in their letter and outlined both the panel upgrade to 5G network and the plan changes. By mentioning only the former in their letter they only arise suspicions when the customers call Telus only to be told they must change their plan if they want the 5G hardware.
