Sorry dude. Of course there are other possible alternatives to dilution. But until they actually announce something, dilution is a possibility. Imho its not "alarmist" to raise a realistic possibility. Not to mention it is a very common way for many startup companies to raise capital.
There is nothing inherently evil or bad about dilution. Just take a look at the article linked below:
