I don't know their motives, I hope there was some tech debt reduction in this redesign and that it's not just a new fancier skin.
ps: also how come they didn't roll out the thing in stages ? anybody in the medical field can tell if doctors or researchers were involved in testing a beta of this ?
There was a beta for a while but it was opt in, I think you could provide feedback but I opted against using it till they made the full switch.
On a personal note, I can still navigate the website as needed, but had to learn how to use the site again. Obviously, full functionality is still there, they just slapped a fancier skin on it with different formatting.
