If you are going to say something, just say it. If you're going to accuse someone of libel, just accuse them. Don't be all passive-aggressive when you're accusing others of being passive-aggressive. It looks kind of like you're projecting a bit, y'know?
In this case, I wasn't making any accusations about Backupify. I was merely pointing out how their external behavior is indistinguishable from phishers'. For all I know they're stand-up guys with the best of intentions, but I object to business models that are based on encouraging bad security practices. They could do everything they do by providing software that verifiably keeps passwords and keys on the user's computer, never storing anything unencrypted in Backupify's AWS cloud. That would be just as useful, and it would be the responsible thing to do, but offering a service instead of software is easier - no platform-support issues. If they're using GPL programs (probably) then they also get to take advantage of the "service provider" loophole to avoid distributing their modifications, and if Backupify ever becomes popular then a service model has better revenue-generating potential. All good for them, so apparently they don't care that it depends on users doing just about the dumbest possible thing security-wise. They might have no intention of abusing their access to users' data, but can they guarantee that every disgruntled employee or contractor will be so noble? Hardly. That's exactly why giving your password to anyone else is a Bad Idea. Business models based on encouraging users to do stupid things are IMO worthy of derision, so I gave them some.
You're not wrong about the issues involved, but the way you went about it was attacking Backupify, not directly for bad security practices, but indirectly through the "Backupiphish" scare-mongering.
And as for your accusations, you started with setting up a hypothetical company that looks like them and commits massive bank fraud, then saying that it "has nothing whatsoever to do with Backupify. No sir, not at all. Pure coincidence." If you want to make those accusations, back them up. If not, write a post about their bad security practices, instead of a post about a (hypothetical) web service backup company that's (ahem) entirely unrelated's crime.
Gee, so sorry I didn't write the post you would have, and chose to approach the issue satirically instead. You do understand satire, don't you? You do understand how _A Modest Proposal_ was more effective than some dry exposition of the underlying issue, right? Maybe my "wrong choices" about how to raise awareness of an issue are the reason that you were reading my blog and not vice versa. Everybody loves a kibitzer.
Maybe I wasn't clear: my main issue with the post isn't that it approached the topic from a non-factual angle, it's that it does so in a way that looks like an accusation of a very serious crime.
The line at the end isn't subtle, it's clearly sarcasm intended to mean the opposite of what it says, that is, that this post is about Backupify. Well, the post is about a company that provides the same service as Backupify but instead steals bank account details.
Unless it's not true, in which case you wouldn't want to, because that would be libel.
