From time to time, a group of researchers split off and make products that are useful right away (as opposed to research focused maybe 5 years or further out), and I think that's AWESOME. Why wouldn't it be great?
Look at some examples from Stanford University: SUN Microsystems was founded in 1982 as "Stanford University Network" created by Andy Bechtolsheim as a graduate student at Stanford. SUN productized RISC systems, NFS, Unix, etc. Really great stuff. This didn't bother or hurt Stanford one bit, just made it a more attractive place for future entrepreneurs to attend/work for a while.
In the same 1982, Jim Clark was an (associate?) professor at Stanford doing research in 3D graphics, and he split off Stanford and formed Silicon Graphics with his graduate student team (Tom Davis, Rocky Rhodes, Kurt Akeley, etc) that they basically had created without taking any personal risk while working at Stanford. Nothing but great news for Stanford, people FLOCKED to join the university that produced that talented team.
A couple years later in 1984, Leonard Bosack and Sandy Lerner were running the Stanford University computer systems and they split off forming Cisco.
A few years later in 1998 Stanford professor Mendel Rosenblum, with his Stanford grad student Ed Bugnion, and some others spun up VMware.
The list goes on and on for Stanford alone.
All these really awesome people came up with solid ideas in academia that were applicable in the next few years as viable products, then these people stepped up to form companies and make products I buy and use every day (or I use their descendant products) and these people formed companies that employed a lot of good people (I worked at Silicon Graphics for four really fun years), putting out solid products and making enough money to let some of us save up and do our own startups in time.
Seriously, this is really positive stuff. Why is anybody afraid of a team stepping up and out of academia? Usually it just means the possibility of a product that will make my life better. Heck, succeed or fail, I've seen some of those early guys back in the University system helping out again and finishing their PhDs they started years earlier when they got distracted (Rocky Rhodes, Ed Bugnion, etc). And there always seems to be a flood of new blood feeding up into the University, earlier successes CONTRIBUTE to recruitment to these Universities, it is a selling point that Stanford has produced some great companies.
If Uber grabs up a lot of great people from Carnegie Mellon, a flood of 18 and 22 year olds will flow in to replace them and get trained up. And I say good for EVERYBODY.
