1. Electronic devices have varying degrees of embodied energy and resource usage - it is incumbent on the end user to justify that usage
2. Electronic devices are designed as attention-sucking devices for selling advertising, and as such, have more negative uses than positive, which makes controlling them as an end user more difficult.
I completely agree with your second point, but nevertheless we should recognize the ease that these electronic devices offer us to train, communicate and also develop profitable businesses.
Training - eh, maybe. I ditched my Garmin and Strava, and have never been happier with my cycling. Some people seem to like the Zwift thing though.
"Ease of communication" - I now consider that a downside. I don't want to be distracted by the possibility of getting a notification at any second, with information of any level of severity.
"Develop profitable businesses" - yes, there is a lot of money to be made selling people shiny things.
