What is the ruling on using a modified forum version, available for free online, after removing its reporting code, given that the owner of the original program is a foreign company and requires an annual payment, and what should be done with the profits obtained if its use is unlawful?

It is forbidden to copy programs whose code has been removed without the owner's permission, although some scholars have made an exception for copying for personal use. Some have permitted the purchase of programs that have been copied and widely circulated, and where it is highly probable that the producing company has already made a reasonable profit. There is no difference in ruling between a Muslim and a non-belligerent non-Muslim, as the property of the latter is to be respected. You must cease commercial use of the program unless you purchase an original copy. As for profit from the forum, it is permissible because it is the result of your own work. If the company is entitled to a fee or compensation for damages, you are obligated to pay for it, and its estimation is to be determined by experts. If it is impossible to know the required amount, you must cease using the current copy and purchase an original one.
