More forgiving licence type

[cs0da]

Do you plan to modify the GPL3 licence to more forgiving one, where the user should not expose the source code which is based on this Knx stack in case of device will be sold on market?
Like MIT licence or apache 2.0?
Even gpl2 would be more useful, gpl3 is very strict.

you can sell devices with GPL software, who told you that this is not possible?

Anyway, changing a license afterwards is nearly impossible.
All contributors would have to agree.

Thank you for the answer!
I know I can sell it, bit the required documentation is more problematic in case of GPL3 as I read.

I would never agree to switch to such a "forgiving" license as a contributor.
Sorry. This stack is open-source and for DIY enthusiasts. Everything shall stay open-source.
However, I am interested how you would handle certification of the stack with the KNX association and how you would handle product databases if you plan commercial products.

Update:
Here are some details about the certification:

Thank you for the answer!
Yes I can understand why it is not a goal about the license type, but it was worth asking.

I'm not deeply in to the certification are, I read some articles about it and of course if I want to create knx certified products with that lib I need the permission of the contributors to send the lib for verification or somthing like that.
(It would be cool to have an open source knx lib with certification)

I've only just begun to delve into this topic.
