CTV picking on Oliver?

What is with today's jumbo text screen positioned directly behind Question Period's long-time host Craig Oliver?  As was it openly revealed a year ago, Oliver has serious visual impairment; this has been present for many years.
Now, I've said before that all persons over the age of 72 need to leave their full-time employments, and particularly when it involves holding a top-level role.  And Oliver is past that marker.
Maybe CTV News' management now feels the same way.  Certainly they will be noticing the upstart of Global's political show with a former, younger, Question Period co-host Tom Clark.  And perhaps there are still some further rumblings after Lloyd Robertson's departure from their weekday national news program.  And maybe there is a little more heat with both of its mandatory carriage cable news channels, CP24 and NewsNet - after further CRTC permitted competition from both Rogers and Quebecor?
Is an old and legally blind, 3rd federal political party associated, news reporting employee therefore just an easy target?
Not only was there a mass of text scrolling immediately behind Oliver.  That could be fairly passed off as CTV being trendy etc.  This was a wall of broken grammar Twitter tweets, presented in an conflicted and pale colour palette, dropping in a decidedly stepped and disjointed line by line fashion.  Even a person with 20/20 vision could not readily discern it.
They may as well have just had a program executive standing behind the show's host mocking hand gestures to the camera's audience.  So I'm not a Craig Oliver fan - but d*mn, that is mean-spirited.
