Maybe Yahoo was a poor example. Substitute instead... idk, airbnb, doordash, or dominoes. I have no specific knowledge there is slack there, but having contracted in IT in a number of large and global enterprise, lack of security and lack of security concerns was all too common, and it stood out more in places that worked with and kept clients' financial information "on file."
AirBnB and DoorDash are Internet companies, just like Twitter. I wouldn't even consider Twitter "a major player in the tech market." Apple, Amazon, Google, Dell, Microsoft, IBM, Tesla, Nvidia, Samsung etc., are tech companies, but not Twitter or Netflix. What technology is Twitter secretly working on?
