In (partial) defence of Adobe Reader...
"The folks at Adobe seem to think everyone's world revolves around their shoddy document reader. It's always checking for updates or getting in the way with startup items. It's a document reader folks, not the centre of my work day! Lucky Mac users get their own reader in the form of Preview. Why on earh can't MS do the same?"
Well, since people often use Reader to view documents from the web, being out of date places the users at risk. So the software checks for updates by default, to protect the users. There is a simple reg file available from the Adobe knowledge base which disables the updater, if it bothers you.
The product is also slightly larger than it could be, because it contains many Acrobat features, which paying Adobe customers can switch on (search Reader Extensions). There are very few things which are truly free, lots of products like this are given away as a mechanism to encourage the sale of paid products. Foxit is no exception.
In this case, you are getting Adobe Reader free so that companies who want to make forms which offer web service and database connectivity, the local saving of filled forms, commenting and more don't need to buy everybody they send a form to a copy of Acrobat.
I used to think of Reader was bloated software, until I realised just how much was possible with the right amount of kerching.
But as for this update, I agree with the sentiments... botched is a good word. No details of security fixes, massive file size, no incremental available. Hopefully they will issue an apology for this debacle.
