I really dislike their aggressive attempts to get new members to send out join requests to every person they've ever corresponded with on gmail. I've gotten many invitations from people whom I'm pretty sure had no idea that LinkedIn was going to scrape their contacts and spam everyone. This happens a couple times a year ever since like 2010? I haven't seen any other tech company do something similar. There is a lot of value in their network, but this is pretty obnoxious and basically dominates my impression of the tradeoffs they're willing to make
