I didn't want to include the much longer list, if we look to more recent events, Google Play Music is in the process of being replaced by Youtube Music, but with way fewer features. I was also a Google Wallet user, and they killed it, Google Notebook, I'm sure I can keep going if I try to remember for a few more minutes.

I still can't get over how they killed Wave while it was still extremely in beta. It didn't hurt users in the same way, but I think it clearly demonstrates their terrible decision making.

Google could've easily occupied the space where Slack, WhatsApp, etc currently exist. They had the technology, they had the team with a vision for a new standard of internet messaging. Instead they just pulled the plug within months.

I was a big fan of Wave but all other history suggests to me that Slack would still have wiped the floor with them due to factors outside of the immediate product teams' purview.
