No, that's different.

What Sleepycat does is called dual licensing. Anyone -- businesses,
individuals, profit-makers and non-profits -- can use the software
under the conditions of the Open Source Sleepycat License.

If for some reason, you don't like the terms of the Sleepycat License,
you can work out a separate license with Sleepycat Software.

I can see how you'd get confused, though. One reason some people don't
like the conditions of the Sleepycat License is that it requires
people who use it to make their source code available. People who
don't like making their source code available are often businesses. So
it might *seem* like Sleepycat Software is discriminating against
businesses, but in reality, they're not.
