Controversial opinion: If you have a distribution advantage there is no shame in copying competitors’ features.
I think Instagram copying Snapchat was the right thing.
And Microsoft should just shamelessly copy Slack’s features without trying to be original.
Example. If you are a music streaming company launching today, instead of trying to be original with the Profile section, or with how the Like button should look, focus on creating a game changing feature like Spotify’s Discover Weekly (Not the UI but the algorithm which powers it)
Coming to Spotify, Every company is a tech company nowadays. But there are only a few like Spotify who are actually leveraging tech (their recommendations) to build a 10X better product, and thereby making Tech is their moat.
