Presumably less secure is not the issue. Buried in the fine print of many of these tools that save you money or do other things with your account is explicit permission to share / distribute / use your data in lots of ways. It's explicitly not secure.

"This is how scammers are now abusing Google Calendar to pillage your data"

"Gmail app developers have been reading your emails"
