Some examples: -- The websites of various airlines (TAP, Vueling, KLM) have often had bugs in them (in the past 2 years when I used them) to the point that they don't allow you to book tickets or log-in with your account. I would say they where broken more often than not. -- Instagram and Google have been deactivating people's accounts (automatically) for no apparent reason. I've had this happen with Instagram 3x in the space of 2 months after which I just gave up and stopped using it. -- Skype, no explanation needed for those who use it. -- Teams fails in many amazing ways no matter how often they "update" it. I've heard stories about the mute button not actually muting, Teams suddenly reversing the order of the letters in your sentence as you're typing in a chat, it just shuts down in the middle of a call, unresponsive, etc etc etc. The amount of productivity these bugs in this software burn worldwide must be significant and the real cost to companies in the form of wasted man-hours is likely higher than whatever they pay in licensing fees to Microsoft. -- Telegram can't handle an external monitor (the scaling gets all messed up causing you to have to restart Telegram to fix it). -- iCloud takes between seconds and an hour or so to sync files even when all devices are on a good connection.
