Yes, if you leave out the number '500,000' it sounds silly, doesn't it.
And the only reason the number of exploits from untrusted sources is 0 on non-jailbroken iOS is because you simply can't install from untrusted sources.
Since you seem to want to compare Apples to Androids, though, here is one that infected 100k+ iOS devices, no jailbreak or untrusted sources required. And another affecting 75k+ jailbroken iOS devices. I stopped searching after finding those two (which took a whole 30 seconds); that it was so easy to find those two tells me there's a lot more to be found if I wanted to invest another half-minute in it.
Let's see, 500k of 900 million Android devices, that's an infection rate of about 5.6%. I'll admit, that's not great, but let's see how iOS fares before we got all uppity, okay? I can't find "in use" numbers, only that Apple has sold over 800k; I know they're not all in use, so I'll do a quick calculation based on market share. Worldwide market share, that is, since the 500k number you're touting is worldwide. So, Android's 81.5% market share means that 1% of the market is a hair over 11 million devices; iOS holds 14.8% of the market, or 163.5 million devices. 175k infected, out of 163.5 million devices, that's a 10.7% infection rate.
So yes, sure, let's assume that other malware exists for iOS, sure there are almost 3x as many infected Android devices, but an iOS device appears to be almost 2x as likely to be infected. Factor in that other malware certainly does exist (every jailbreak is an exploit and many jailbreak utilities have been bundled with malware; little reported but anyone involved in the scene knows, always get your jailbreak tools direct from the author, but even that is no guarantee). In short, the 175k number I used is smaller than it should be, making the 10.7% infection rate I came up with a fair bit smaller than the real infection rate, as well.
As a user of a single phone and a single tablet, running the less-likely-infected platform means I'm less likely to be infected. Period. That said, I greatly prefer iOS over Android on a tablet and absolutely love my iPad. I don't do anything mission critical on either device, so my exposure is limited in any case, but I'm a little more lax with my more secure Android phone than I am with my less secure iPad.
It doesn't at all sound like the result of bad philosophies colliding, thus breeding bad behavior from a massive number of customers.
Correct. It really doesn't. unless you consider freedom a bad philosophy. Of course, with freedom comes responsibility, as in you are responsible for what happens when you misuse the freedom to install crap on your phone. Seriously, rather than volunteering to have our own freedoms stripped from us because we refuse to connect our actions with the consequences they bring, why don't we all just behave like the adults that we are and own out own liabilities? Android lets you do that, while iOS does not.
Oh, just wanted to mention since I'm somehow a douche for your laziness, you replied a full hour after the link you asked for was presented.
You're not a douche because I loaded the page long before that link was posted (not laziness, BTW), you're a douche for a whole slew of other reasons, many of which also apply to myself. So I didn't refresh the page before posting. We all do that, your point? Welcome to Slashdot.
Fandroids are especially vulnerable to SEP.
They also wouldn't own an iPad and two MacBook Pros. I guess you aimed your anti-Fandroid ray at the wrong guy.
