Hi Angelsoul,
you're right,to open native files created with the latest CC software you’ll have to have a CC subscription yourself.
However, always provide printing/service places with a high res (certified) pdf file instead of native CC files.
Oh yes, if you are a creative professional making money with Adobe’s software then indeed you have no choice but go with the Adobe flow.
Be smart and creative, you even can’t buy a daily bread for that price ;-)
