It makes large difference if you're well paid. You can only buy ~$650 worth of stuff from $1k in paycheck, but you can expense full $1k of stuff in the other scenario. Of course, you could argue that if you're well paid, you can spend additional $500 of your own gross pay to top up that $650 to full $1k, but clearly Shopify doesn't think this way, because if it did, it wouldn't give any extra $1k in the first place, and just tell their employees to get what they need and pay for it themselves.
