Dropbox Public Folder Alternative - so I can copy public links from the Finder? I just got an email from Dropbox saying that they are disabling the Public folder feature as of March 15, 2017 and I'm looking for a (free) alternative.

I use the public folder quite extensively, especially to "attach" screen caps/recordings in web forms or emails when submitting an attached file is not an option.  I have probably even linked a few files from my blog.

Apparently, you can still generate public links to specific files with Dropbox, but there is no longer a way to share a group of files publicly to browse, without generating a link to each one. So you can't just drop files in a public folder and instantly allow anyone to browse them. Sharing a folder is now only possible to specific users via entering their email address.  Any files in your public folder which did not have links generated are no longer public.

So I would like to find an alternative cloud drive service that not only has a public folder, but also allows generation of public links via a Finder contextual menu.

I discovered that Google Drive can generate public links, but there's no way (that I know of) to get the public link via the Finder.  I've used MEGA and Copy in the past, both of which could generate links from the Finder.  MEGA folded and I don't remember what happened with Copy, but I assume they put up a pay wall.  I was just reading through the OneDrive site and could not determine whether they even had a public folder, let alone a way to get a public link to a file from the Finder.

I also have searched a tiny bit for some google drive API documentation to see if there's a method I can use to create an automator service to create/copy a public link.  Couldn't find anything.
I don't know if we are taking about the same, but I used to use also quite much the public folder but since I can get a link to any file in my Dropbox, right clicking on it, I am not using it so much anymore and have my file in proper folders. 

Have you tried right clicking and getting a link to file in your Dropbox but not in your public folder?
