proprietary software is worse than open source, but not for the stupid freetard reasons
both are programmed badly and barely fucking work, but proprietary software adds a bunch of licensing bullshit on top that breaks it even more and requires you to handhold your purchasing department on getting the correct loicense and count user/machine seats and manage renewals and a whole bunch of other pointless busywork
and then there's the support problem. there will be an out of touch boomer in a leadership role in your company who thinks having a support contract means you'll be able to call the engineer who wrote the program and work out any problems in 10 minutes like it's 1991 rather than being sent into an endless loop of "your call is important to us, please remain on the line for the next available representative" and then blown off into an endless cycle of "hello sir kindly do the needful and upload the latest logs" and "we are analyzing the logs".
