It might flavor the straberries, or maybe the straberries choke out the garlic. It's hard to say. I haven't seen many explanations as to why things are incompatible. Sometimes they just compete for the same nutrients.

Plants give off chemicals. Roses like the chemicals given off by onions, so roses and onions are good companion plants. I don't know specifically about garlaic and strawberries, however, both like acid conditions.

I use santolina bushes as insect repellants in my strawberry bed. I have a raised bed, about sixteen feet long by three feet wide. I have three santolina at equal distances. Haven't had any problems with insects in that bed since I put in the santolinas.

I was asking myself the same question, so I did a couple of searches and http://www.westcoastseeds.com/topicdetail/topic/companion-planting/
Here they say it is okay to plant them together.
