Can I use the code of a premium free WordPress plugin in a commercial project?

Question

Law in IT

Recently came across wp-premium .
Paid plugins in the public domain, and oh my god, acf-pro (License: GPLv2 or later) is among them. But wait a second... wait a minute... can I just take this code and use it in a commercial project?
If not, why did you post it? Provoking poor developers or something, it's too cruel...

Answer 1

There may also be an exploit, malware, and other specially wired tricks from the distributor. Because null plugins have already brought pain to their users more than once. And even problems arose on neighboring sites of the hosting account. Where there is no null.
Read - on the Internet there is a lot of information on this subject.
Well, on the topic of the question: using in a commercial project - you substitute your commercial resource (this is a time bomb). Are you sure that there is no malware from the distributor? Or maybe it is well hidden and there has not yet been a signal for it to show itself? Or is it not yet in this update, but will it be tomorrow? What is your level of knowledge - to independently conduct an audit? And so before each update. Do not forget that there is no free in the world. Everywhere has a purpose.
Well, as they said above, you will not receive technical support from the developer, timely updates (what if they found a hole? The developer will fix it quickly, and the distributor of these files will not respond promptly. Until the turn comes)
And as a final - the plugin may cease to exist. Or the author will quietly sell it to another company - as an unprofitable asset. And the new guys will introduce it there ... Well, we read everything from above again ...
So - do not support the developer.
Well, if you decide to distribute it - selling it - it can turn back to you. Do you think why those guys give through github? Don't they sell?
The second aspect is morality. Just like in politics - it can affect your reputation. So ask questions, but try not to express your position in the comments that this is "correct and true" and "why not." The Internet remembers everything. And if your commercial project shoots, then it's in your foot. It is because of the use of the fact of someone else's work that it will alienate partners and investors. Or you will not be able to find a buyer for your commercial project - if you want to sell the resource. There are many options for "what could go wrong".
ps Microsoft bought a github - so I think there will be a wave of bans soon and such an account will be banned. The abuza has not yet reached him. Until they do. On what basis? Based on an authoritative victim.

Answer 2

It all depends on the license. The code may be in open use, but the rights to it are determined by the license. Didn't read the links, but that's how the world works. And if the plugin does not send statistics to itself about who uses it, then use it to your health

But wait a second... wait a minute... can I just take this code and use it in a commercial project?

Yes, but:
The issue of payment comes down to receiving the plugin code from the developer (the GPL license does not prohibit selling the code, even someone else's) + a license key gives the right to support and subsequent updates.
Those. in most cases, you are not being sold code, which in the modern world can be found in 5 minutes of googling, but support and the ability to quickly receive new versions of the plugin from the developer.

Reading the license terms is not fate?
