[20] To maintain its independence and transparency, Future Forward has adopted a funding model that depends solely on contributions from its members and supporters.

[22] Thanathorn, with his business background, youthful image, and political perspectives, has attracted international media attention, drawing comparisons to leaders like French President Emmanuel Macron and Canadian Prime Minister Justin Trudeau.

[23][24] In Thailand, media often labels him as the "billionaire commoner," highlighting his role in challenging the country's social class system.

"[26][27][28] Regarding legal matters, Thanathorn, along with Jaruwan Sarankate and Klaikong Vaidhyakarn, senior members of his party, faced charges under the Computer Crime Act.
