Absolutely - I have noticed the same in effectively all startups. I'm not even out of high school yet, so take my words with a pinch of salt, but my guess would be all companies may start out as 'enthusiast' brands, of sorts. Since their market is well defined and not very large, once they outgrow their market, investors who want higher returns and more revenue probably push them to expand outside their original market, thus reducing their focus on the original market.

Feel free to correct me if I am wrong. Also, what is CyanogenMod? And why did Ubuntu add Amazon products to its search results?
