No. There are hundreds of programs that easily read and create PDFs. OTOH, reading .docx is a pain. Far be it from me to defend Adobe, but PDF is nothing like MS Office formats.
Ooh that’s not fair. Many PDFs don’t conform to the spec and how Acrobat processes them is completely undocumented.
It was funny for a few years when Apple just released Preview, and it rendered many PDFs better than Adobe's own Acrobat
Yeah it's a great app, one of the big reasons I still use MacOS - but there's certain features which you still need Adobe Acrobat for, I know to fill in the tax forms for my country you do.
I mean the rendering part. AFAIK there are no that many renderers.
