“Pantone was unable to actively update the library to correct any changes to the color data or to update it with new colors,” Cheng told CreativePro. “We had to find a way to address user problems regarding these outdated libraries.”
So if I'm reading the article correctly, Adobe products were running on an outdated license for the last few years and were not able to get the newest PMS colours from Pantone, so Pantone decides the best way to deal with that is to pull all the pantone swatches from adobe products and start charging a monthly fee for them. What they should have done is left them alone and offer the up to date library as an add on service to those who need them. I can count on 1 hand them number of times I've been given a pantone that wasn't in my 10 year old swatch book.
This is going to really underline the issues with Adobe's subscription only always connected business model, people who subscribe will be forced to have their pantone libraries removed. My 4 year old copy of coreldraw will continue to work just fine, and at a 1 time fee of $400 to boot.
