What is the legal ruling on receiving money in exchange for liking videos, along with paying a sum to the company at the beginning of the year that is returned at its end, and is it permissible for the company to use this sum for its development?

The amounts imposed by the company as a "seriousness guarantee" constitute a loan from the customers to the company, and this loan stipulates a return, which is the commissions in exchange for viewing. It is not permissible to combine a loan with a contract of exchange, such as sale or lease, based on the saying of the Prophet, peace and blessings be upon him: "It is not lawful to combine a loan and a sale, nor two conditions in one sale." The reason for this is that it is a means to usury, because this loan draws a benefit for its lender.
