Color profiles that you have created yourself are specific to the hardware and lighting conditions that you calibrated for. A display that has been powered for a few hundred hours is going to have a very different color profile to a similar display with the next serial number that has been lit for a thousand hours.
This means if you share your color profile with somebody, you might be getting them closer to calibration, but it’s misleading at best to say that their display is calibrated.
Similarly, unless everyone has recommended controlled lighting (no sunlight from windows, black walls, daylight bulbs etc.) in a room where viewing and editing images takes place, sharing a profile that you created in your own specific lighting conditions doesn’t make a lot of sense.
You should carefully check the redistribution conditions for profiles downloaded from vendor websites or that were created on your behalf.
