• having profit, rather than artistic or other value, as a primary aim : their work is too commercial.
3 (of television or radio) funded by the revenue from broadcast advertisements.
4 (of chemicals) supplied in bulk and not of the highest purity.
Gain;
[mass noun]
1 an increase in wealth or resources
[count noun] :
shares showed gains of up to 21 per cent
So, simply receiving a payment does not constitute either something commercial or a gain, you only have those two, once you profit.
