I'm sure that's unintentional - don't blame the university, but I'm sure Nest and Ring anticipated their network of cameras worldwide to generate enough notable videos of unusual or funny antics that would be shared, so they shove their logo on their videos.
Some people claim you can have the watermarked logo removed but you have to contact Google/Nest directly. I'm going to do that right now (I have 5 cameras... which I bought a week before Google announced they were locking-down the Nest ecosystem and web-service, so I now refuse to buy any more Nest products and I recommend Ubiqiti gear instead now - Ubiqiti have everything Nest does except a thermostat and smoke detector (but they do have a temperature sensor product ("mFI-THS") - and an adapter to bridge any RS-232 connected device ("mPort"), so you could attach an RS-232 controllable thermostat that way - it just wouldn't be as sexy as Nest's giant metal knob).
this reminds me somewhat of the camera software on low-end android phones sold in the developing world which watermarks every photo with "shot on... (blah blah trademark name)", because they trust that 90% of users won't know to look in the settings to toggle off the option. Or don't care. But hey, free advertising right?
