Yes. All software companies now seem to go through the same cycle. Offer a good product at a cheap price or free. Build market share. Start adding features for a fee. Start packaging those features, so you can't buy the feature you want without buying others. Move to a subscription system. Keep updating to add more monetisation. Start hiding original features behind paywalls. Start to die off.
Obviously, there is the user as product version too which is similar but with ever worsening waste of your time rather than money.
There has been very limited improvements from a general user perspective in either phones, PCs etc over the last decade. It's been incremental cosmetic only for many. An iPhone 4 or old Nexus phone does most of what current phones do. Graphics has improved for gaming, but games are often less fun and more grinding and cosmetics. It's infuriating.
We should have a vast wealth of knowledge that is easily accessible. Instead search engines are programmed to sell to us rather than inform us. I think the biggest part is the disparity of knowledge. If Facebook Google etc had to document how much, to the cent, they made off each customer and each search, users would be more savvy and perhaps more willing to avoid them. I think Facebook will try to avoid the paid users in Europe as they will likely be less valuable. If the make their price high enough to cover the same revenue, they will likely have no customers and spook existing customers.
