Hell, had they stuck to their mid range Optimus stereos and expanded their security equipment/camera stuff it might have been enough to keep them viable. But when they went heads up in the cell phone market, it killed them.
There are several component companies thriving online to service the DYI market globally where people still do build things. they could have went that route. But I agree completely. Here, Me, you and few others are likely all thats left that even have an interest much less the ability.
I remember the days when they had Arthur Fiedler, the famous conductor, hawk their stereos.
