Bill shape: jump versus flat

SiteGround's ownership cost is dominated by renewal months at $14.99/mo. Kinsta's ownership cost is a straight line at $35/mo. Neither pattern is “more honest” in the abstract — they are different products. If you hate surprises, flat wins psychologically; if you hate absolute spend, SiteGround's $408 still undercuts Kinsta's $1,260 by a wide margin in this file.
