I have the option to buy the “Meta Box” plugin (plus all extensions). From the third person, not from the Meta box company. I only Buy plugins without a “license key” without the possibility of updating. I am curious if it is legal. Maybe one of you could explain that. On “Meta box” under “terms & contition” is written:
1. Every single extension is under GNU GPL v2 or later.
2. Always keep the credit to metabox.io (linkable)
3. Premium extensions must not be included in any free product or released/delivered free of charge. Meta Box has eligible to ban permanently the violator without any warning.
i. License of individual premium extensions / bundles is valid for one year from the date of purchase, except the Lifetime Bundle.
ii. Lifetime Bundle has no time limit.
i. You are eligible to get updates and support until the license be expired. After expiring date, you can continue using the plugins without any update or support.
ii. We will remind you to renew when the expiring date is coming soon or passed.
