Envato is also taking a certain market though they are often the tire kickers who think they can do it themselves. You see a few of those who get so far but can't finish it. The instant their content doesn't match the length of the default content it starts to look bad or the template displays 4 key services, they have 5. What I find infuriating is the freelancers (or displaced marketing people) who just sell templates and even their own site is just an off-the-shelf template. The SEO space is similarly flooded with marketing people who can run SEMRush to get a report and spam your client base daily with long tail keyword suggestions they could get them ranking number one for.
There is a new type of customer who want something custom and vehemently don't what a template as well.
The big thing is mobile compatibility is still hard and hosting/security is hard. New browsers break stuff and many corporate clients still need it to look passable on XP. Customer Service is key and building a loyal customer base who you look after, will weather you through any slight change in the market.
