I was born during the baby boom era. I've concluded that "boomer" has long since lost its literal connection to "my" generation. It is now used as a metaphorical disparaging label that means "selfish and clueless because of age."
It's kind of like the trope of technologically clueless grandparents. At this point, the only grandparents who are technologically clueless are those with the same mindsets and experiences as all the GenX and Millenial people who are technologically clueless. And there is certainly no shortage of them.
The problem is that they are the majority in every generation. The majority of people don't understand the distinction between http and https, that PMs on Facebook are readable by Facebook staff, or that there in an entire sector dedicated to collecting and selling personally identifiable information.
It's hard to drum up support for a cause that most people can't even understand.
