Canon Community

I'll probably get that too by saying something is Shady. 

They do but not all models that are having the same issue within days of each other.  Canon offering to buy new printers as a fix is Shady business.  

If the only solution is buying a new printer,  trust it won't be a Canon. They did something over the last few days to make thousands of printers incompatible.  Shady to Me there's so many people having problems all at once.
