I've never actually said it out loud, but I mentally pronounce the meme doge to rhyme with rogue. Although doge-as-in-Venice is slowly creeping up on me.
I don't mind memes but it's funny to see people get them wrong - a tainted meme if you will. So many people pronounce pwn with a P-sound. It's really just about mis-typing and p/o being close to each other on a keyboard. Pwn is pronounced exactly like own. Of course there are people who grew up after pwn was already popular, and learned it wrong from other people who had a misapprehension concerning its pronunciation.
This was exacerbated by the relative lack of VoIP or in-game voice chat systems when pwn was emerging. If people had been able to hear the pronunciation, they would have been much less likely to learn and transmit a tainted meme. Of course, the timing would have to be perfect. The very reason why pwn emerged was a requirement to type instead of voice chat. If voice chat were around to reduce the incidence of the tainted meme, the meme would have never emerged in the first place. It would have to arrive and circulate, growing strong in people's minds, but then voice chat would need to supersede typed chat during the meme's heyday. There's probably a couple years where that could have happened.
There were also people making videos purposefully mispronouncing it to make fun of people mispronouncing it - and in some cases perhaps the video producer was actually operating under a tainted meme and was earnest, or else simply making fun of internet gamers without understanding the actual meme.
That's not to say a meme can't change: putting your own spin on it is half the point of a meme. But the other half is transmitting it with an understanding of it. If you're simply ignorant or were given a tainted meme, you can't be doing more than half the job.
As a person who was around when the meme started, I tell you: if you pronounce it "pohn" because you think that's how it's pronounced, you have a tainted meme and you should stop spreading your version.
