I held off on Windows 10 for as long as I could until Adobe, and therefore my job, required it. Now this nonsense. I hope this isn't the start of them joining on the web DRM bandwagon.
I don't get why PDFs are so hard to open. The format has been around for ever. Why does Adobe have such a grasp on it, and why isn't it as common to open as a txt?
There are free programs that'll open it, but it's few and far between. It's a pain in the ass to find one.
Edit.
I looked it up. Adobe created PDF, but:
Anyone may create applications that can read and write PDF files without having to pay royalties to Adobe Systems; Adobe holds patents to PDF, but licenses them for royalty-free use in developing software complying with its PDF specification.
Foxit Reader has decent PDF editing built in. I use it all the time. I think they call the pen mode "comments", but you can also load your signature as an image file.
The only time I use (pirated) Adobe Acrobat is when I need to edit existing content in PDFs, like fixing layout or editing text.
Happy PDF-XChange user here. Fair pricing for home users / small businesses, great feature set, stable, regular updates that actually improve the product.
Actually had complaints of less-technical users at work when by some weird accident the Adobe product returned (sneakily bundled installer?) or when a Windows decided that PDFs are to be opened with Edge now, because the users wanted PDF-XChange back. Normally users either don't notice or don't care.
On all my Macs, Preview is set as the default app for handling PDFs, and I use it for signing, adding text, rearranging and deleting pages; works flawlessly. Fuck Acrobat Reader / Pro.
If I need to do something more complicated, I'll open it in Illustrator.
