Vendor lock-in occurs when a customer becomes dependent on a particular vendor for products and services, making it challenging to switch to another provider without incurring high costs or inconveniences. The use of proprietary technologies is a fundamental component of vendor lock-in, as these technologies are designed to be unique to the vendor and often require specific expertise or investments in that vendor's ecosystem. This can create barriers to migration and lead to increased dependency on the vendor's offerings.

In contrast, advanced customer relationship management tools, high-performance computing capabilities, and open-source software solutions do not inherently result in vendor lock-in. While they can enhance customer satisfaction or performance, they do not create the same level of dependence as proprietary technologies. Open-source solutions, in particular, promote flexibility and interoperability, which are counterproductive to the goal of vendor lock-in. Therefore, the focus on proprietary technologies as a barrier to switching providers highlights why they are essential for achieving vendor lock-in.
