Have you ever heard of an online marketplace called PDD? It's similar to eBay, but the products sold on this app are much cheaper than other platforms. The owner's strategy of offering subsidies to gain a competitive advantage and attract more users has been successful in terms of gaining a large user volume and cash flow.

However, as a user of this app, I found that there is a price beyond just the cost of the products. When I installed this app to buy an expensive textbook, I was bombarded with ads from all directions. When you open the app, a full page of ads pops up, and it's not always clear which one will actually close the ad. The app also uses some absurd tactics, like making new ads pop up every time you shake your phone. It even tracks your operating habits and uses this information to try to trick you into clicking on ads.

To make matters worse, the app illegally collects users private information through vulnerabilities in the operating system. As a technology enthusiast, this infuriated me. So my friends and I decided to take action. We made a complaint about the app to the app stores. And thanks to our efforts, major android apps and mobile phone manufacturers now display warnings when you try to install the app.

As consumers, we have the power to speak out against these practices and demand better from the technology we use every day. I hope that companies like PDD will take a more user friendly approach to marketing and prioritize their users needs and privacy over their own profits.

In conclusion, while PDD's marketing strategy may have been successful in gaining a large user base and cash flow, it comes at the expense of users privacy and user experience. Let's all take a stand against these practices and demand better.
