You could argue that it is a loophole but thing is due to the current world economy which build on debt . It is very hard or rather impossible to earn while avoiding or getting into a interest based contract . Our religion is flexible in these matters unlike how media potrays us to avoid unnecessary hardship to honest believers. We are instructed to avoid direct interest payments as much as we can.
Now , back to your question. The delegation payments unlike HBD interest aren't fixed and differentiate daily based on daily reward pool and curating skills which is why this is treated as investing in a profitable business where i have hired someone to do delegation for me and he pays me after taking his cut (salary).
Whereas HBD is a direct interest contract with fixed payments no matter what happens.
To summarise, the possibility of less profit or even loss (missed payments due to no upvoting as an example) plus involving a second party along with a transaction of upvoting makes it kind of a business as oppose to fixed interest payments in HBD where no transactions are done except for me receiving payments.
Hope I was able to explain clearly since my first language isn't English. It may seem confusing but for Muslims we can judge and differentiate easily .
Thanks for taking the time to explain it for me.
Much appreciated :)
