Why such services still exists ?

Why such service providers like StatCounter, Webstats4u still exists ? especially when we have Google analytics that can handle five million pageviews month for free while others will lock you at 250.000?

not to mention the very professional and detailed information that Google Analytics can provide while others simply doesn’t have it or lets compare google service reliability to other small providers like the mentioned above?

The question that I’m trying to answer is, Why such small providers still exists when the big are there and for free and Why people still uses and tries those service while we have Google analytics?

Weird isn’t it ?
