The i-line of products was already well known by the general public at the time to be synonymous with Apple. iTunes, iPod, iPhone ... those were normal english words prefixed with an "i". People wonder why Apple didn't call their watch the iWatch. This is a much different thing with "mastrodon". It's not a word people are familiar with, has enough syllables to sound funny, and gets combined with other nonsense words people aren't familiar with. Compare that with something like youtube subscribers, posters, tweets, etc. which are all basic words. Mastrodon's situation is that it reeks of being engineer designed. That's not a good thing if your goal is to reach a mainstream audience.

I think you're skipping past the word "pad" which is what people thought was weird, not the I.

Toot is as much a basic word as tweet, I think you are just reflecting your own bias towards words from products you already know.
