This might just be the quote of the decade! Yes, I know I'll get downvoted.

Not to bring my sour notes from the discussion on the just announced Sparrow team acquisition but the Acrylic blog post mentions that the products and services remain and the wording makes it appear to be a hire(not an acquisition) if that makes you feel any safer.

on the blog post Dustin mentions that FB is not buying the software, so its a pure hire

Prevent them from creating facebook competitors?

They do, subtly. It's only major overhauls that are rare. However, I think they'll be working on mobile apps a fair bit and the subtleties of interaction, since Google+ has grown in leaps and bounds through major design overhauls (both the new app and web interface are very good looking and good to use) and flashy ad campaigns. I guess they're trying to pre-empt the effect the relatively good-looking Facebook had on disgruntled MySpace users jumping ship from over-customised profiles.

You could switch to 1Password and yes I realize this would cost something though for the information in question revenue to support ongoing development and maintenance seems reasonable. The AgileBits folks are very solid and I don't see them being aqui-hired anytime soon, and I've used 1P for years with little to no trouble.
