Gantt Chart by MAQ Software

Hello ussenova ,

Vendors are free to change their offering and terms including pricing as they see fit.  Presumably this for any business owner would be viewed as a business expense without further concern.  Consider reaching out to the vendor to discuss this further.

Hi, ussenova 

There are many visual effects available, both free and paid. You can also look for free alternatives that offer similar features. If you want to continue using the advanced features of this visual, you'll need to purchase a license.
