How do you control
how customers use your product?
Short answer –
You can’t.
Yes, you can advise customers,
build preventative measures
into your product,
put warnings on your marketing,
but the customer can ignore
all of this
and do whatever she likes.
As a best selling writer once told me
“Once you have your story published,
it belongs to the reader,
not you.’
Once your product is sold,
it belongs to the customer.
My advice is,
unless the customer is physically hurting themselves
or others
by using your product incorrectly
or for other purposes,
leave them alone.
And consider tracking these different usages.
They might be another possible market
for your product.
