I have Office 2007 (and 2010) which I never update) and about a couple of months ago they stopped working (I expect as a process to get me to update to office 365 - NO CHANCE). I use Libre Office - a learning curve but very similar to Office.
Similarly my GPS (SYGIC) offers me an "update" to premium for a very low price but I know if I bite that will be an annual subscription as opposed to my "lifetime" purchase for my original product and who knows what the next years "subscription" will be - I have asked but no answer.
I understand these companies have to make profits but now they want me to pay for their mistakes.
