Part 1 of 3. Some are lying. Most never have to, because they are paid by the vendor whose product they are recommending and nobody has to tell you. The tells that say you are being sold to rather than engineered for, and what never makes it onto the shortlist.
Part 2 of 3. What actually gets built once the paperwork is signed: cloud for a business with one building, the box they will not be talked out of, the basics that were the thing you bought, and the agent on every machine that answers to somebody else’s console.
Twenty years back you bought software and the copy was yours. Now you rent it, and the supplier sets the terms. Part 1 of 8 walks through how that happened, and why every step made it harder to go elsewhere.
Once moving supplier is hard, the costs change shape. The price follows your exit cost. Profit is declared in one country and earned in another. The law follows who owns the company, not where the building stands. Part 2 of 8, in plain language.
