The sheer amount of salt in the medium comments because of Electron is astounding. Never had any memory hog issues with Slack. Have been using it extensively for over 2 years now. Works fine on my 2010 laptop as well!
Never used twitter. Just made an account using work email to test twitter login. Didn't do a single thing yet. And my account gets blocked for 'suspicious activity' and they want my phone as well. What a shady company.
I had the opposite experience. Uber has customer support built into the App. I was also billed twice and just followed the instructions in App that created a ticket. Got my money back in 2 days.
