Hi there. I wrote the article. You bring up a fair point but unfortunately there isn't any other public data of high quality that can be referenced. I hit LinkedIn's APIs to try and get data on historical job postings for new roles containing "growth hacker" in it but the data is really poor and not useable. I'm also writing from experience + anecdotes having worked on growth for 10+ years and advised a variety of consumer companies on growth. The anecdotes suggest to me it is falling out of favor. I wish there was more data to reference otherwise I would have.
Not sure. Chatted with a few other devs and they shared similar experiences when working with their APIs. The biggest issue is that prior job postings data isn't expose on the API so you can only see current postings, which wouldn't be useful in terms of showing trends, which is what I hoped for.
