Claymore doesn´t build the algorithm´s, he only made a front end and small improvements.
In case of monero / cryptonight, the algo was build by w0lf.
Claymore only use the algo from w0lf, and receive so much.
w0lf only receice the bounty for this job.
Let me calculate

no bounty ... nothing for the bitstream-dev.
Any truth to this? I'd appreciate if you could post a reference link maybe to show maybe how this happened?
This is why dev fees are now preferred over the bounty and one-time fixed costs. Look at all the mining software out there, the best ones are those that have a small dev fee embedded in them. Without dev fees, developers are less motivated to work on improving the software.
