This is a most excellent place for technology news and articles.
You have the correct idea, but it's way too late for most people. This "pre-selection" made by most services have been in place for a long while, and these days people even complains when they are not fed with it.
It is a sad state of affair; thankfully at some point enough people might move away from these automated suggestions, but I'm not holding my breath.
