You have to check really carefully though if you use annual paying for things like that.
For example: Office 356. As long as you pay your annual payment, all is fine. But when you decide to stop, then you can open the documents and so on made with Office 356 just fine. But (of course) you can not alter and safe them any more, making Office 356 a kind of ransomware.
In my opinion these kind of annual payment things are fine when you have a short project of some kind. But when you want to use it long term, then buying is of course the best option.
Or indeed just a download (which of course is very very very very wrong

)
