Kinda related, in the company I used to work everything was done in SAS, an statistical analysis software (SAS duh) that fucking sucks. It's used to be great, but once your on their environment you are trapped for fucking forever. I hated it and refuse to learned it over what was basic for my daily tasks. A couple of months I moved to another company that used to pay a consulting firm for my job, so my boss and me had to start everything fresh and the first thing we did was to study what are going to use as statistics software and I fight tooth and nails for Python and one of the points I pushed was that if in the future we decide to move out of Python we could easily can do it, while other solutions could locked up us with them.
