It sounds like more than that
If you read between the lines then this is an instant pay option and not truly Capitec Pay. Note that Stitch is not actually an officially supported channel in SA and charges extra fees as well.
Capitec started blocking eft payments directly to (crypto) exchanges. The exchanges were told to now use capitec pay. The issue is that the exchanges had to contend with extra fees, and at a minimum it was a 0.55%-0.70% commission whereas to receive an EFT was free. This was crazy and the industry revolted. Capitec saw the error in their ways and very generously (/s) capped the commission to R7 per transaction.
Stitch's instant pay option uses Capitec Pay outright from what I can tell

Yes the exchanges end up paying that R7 fee as well as some stitch fee, while it used to cost them R0. Capitec maintains that it is for security reasons as they can now trigger a face scan for these risky payments.
