oh man... the video and template is 99% similiarity.. thats unfair..
and its free , u dont have to buy it
since the OP said that you can use template and use your creativity, why you called it unfair? you can submit your work using template or not. the OP said that you can submit your work countless times.I know and feel your frustration. if you want to submit using the template just doi it, but if you proud about your original content just be confidence. i don't know the templates are free or not, but finding the idea for their videos is so difficult, also editing the template and the render time for one video will take a few days, especially if they make a good quality videos (1080p or 4K).
Appreciate, using readymade template is not the creativity. If you can make your own template, that's called creativity. Lots of user just did that. Used someones readymade templates, and producing like their own creativity.
