I'm also using the MX Ergo, but I replaced D2FC-F (made in China) with D2F-01F (made in Japan). So far, it has been working great, and I love how it feels compared to the stock switch. The video linked in the article also mentioned (in the description) that D2F-01F may last longer electrically since it's micro-load rated (1mA instead of 100mA), so I guess I'm safe for a while (although it's only rated 1M mechanically).
