In my uni, I strongly forbid use of any proprietary apps, as much as possible. Please forgive me, I do agree software devs needs to eat ... etc. but let me explain.
We all moved to macs in the last 5 years, which means when I upgrade from mountain lion to Mavericks to sierra, we need to get a BUY Endnote. Every second major version of OSX needs and new EndNote. Even with academic license, it costs, about EUR 600 for every device. 1 Prof, 2 Staff scientists, 4 postdocs, 6 PhDs (charged a bit lower EUR 200 per year). You calculate. There are universities where Endnote is cheaper but subsidized by the bulk-contracts.
Oh yes, we do use MS-office. Atleast MS does not force us to buy new MS-Office for every OS upgrade. Also remember, that grants pay mainly for equipment and rarely any/expensive software.
As other posters indicated, mailing-lists + proper filtering is the optimal.
